What you do is if you are on the youtube wesbsite, you copy and paste the embed code. Then if you make a new blog posting, on the upper right hand corner on your editing options like by text, video, bold, italics etc. you will see something that says like "edit html" if you click on that, you will see a regular text box like a posting on your blog and you copy and paste the embed code into that box, and once you have done that, if you reclick the "edit html" button it should be there if you post it. If you want to add text in addition you do the same steps, and then you click on the "text" tab and enter your text there. You can also enter it through the "edit html" option also. Hope that helps.
